Wildcard for a domain

[aacplus]

I buyed a domain that can't be transfered to my hosting company due to his extension , Untill now i setup the wildcard adding a "*" in the dns records but now i don't know where to edit wildcards , where i buyed the domain or where i have the hosting account?

If i point the domain nameservers to my hosting account nameservers i have no option for the DNS records , i have this option only if i use the default servers from where i buyed the domain , but don't work wildcarded !!! Maybe is something ...so easy but is the first time i do this....so how to creat a wildcards on such a domain?
